Red teaming, in an information security context, is an adversarial-based offensive activity against an organisation's assets, whether this is infrastructure, applications or people. Red teaming is a specialised penetration testing service offering wherein the attacker assumes the role of an advanced threat actor and attempts to compromise agreed upon components inside the target. The threat actors use Tactics, Techniques and Procedures (TTPs) in their compromise campaigns. It is designed to be stealthier than a typical penetration test and test the defences of a network against a persistent attacker. It is also goal driven to provide focus and guide the test towards what the targeted organisation sees as its most valuable assets rather than the common misconception of "get domain admin". Mitre's ATT&CK framework, provides a comprehensive breakdown of all the different tactics in a red teaming engagement and outline of all different techniques inside each tactic.
